λ0,

is the free-space wavelength) metallic strip (patch) placed a small fraction of
a wavelength (h << λ0,
usually 0.003λ0
≤h ≤
0.05λ0)
above a ground plane. For a rectangular patch, the length L of the
element is usually λ0/3
< L < λ0/2.
The strip (patch) and the ground plane are separated by a dielectric sheet
(referred to as the substrate). There are numerous substrates that can be used
for the design of microstrip antennas, and their dielectric constants are
usually in the range of 2.2 ≤ε0
≤
12. Often microstrip antennas are also referred to as patch antennas. The
radiating elements and the feed lines are usually photoetched on the dielectric
substrate. The radiating patch may be square, rectangular, thin strip (dipole),
circular, elliptical, triangular, or any other configuration.

Coaxial-line feeds, where the inner conductor of the coax is
attached to the radiation patch while the outer conductor is connected to the
ground plane, are also widely used. The coaxial probe feed is also easy to
fabricate and match, and it has low spurious radiation. However, it also has
narrow bandwidth and it is more difficult to model, especially for thick
substrates (h > 0.02
